Other than database backends supported?

[Konstantin Chuguev <Konstantin.Chuguev@dante.org.uk>]

Hi,

Looking through sources of OpenLDAP-2.0.1, I am concluding that there is
no support of other types of backends/plugins than for databases there.
Am I right?
(Searching in mailing list archives did not give me an answer.)
How can I implement a pre-operation action like one described here:
http://developer.netscape.com/docs/manuals/directory/plugin/intro.htm#1021815
?

Creating a new slightly modified back-ldbm for that purpose is not an
efficient solution, I think.

Thanks,
    Konstantin.
